KNOTTING DEVICE FOR GRAIN-BINDERS.

SPECIFECATIDN forming part of Letters Patent No. 372,506, dated November 1, 1887.

(No model.)

Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Improvements in the Knotting Devices of Grain-Bindersnamely, an Automatic Gord- Supporting Finger therefor-of which the following is such a full, clear, and exact descrip tion as will enable any person skilled in the art to construct and use the same, reference being had to the accompanying drawings, forming a part of this specification.

My invention relates to the k nottingdevices of that type ofgraiubinders generally known as the Appleby Binder, which is shown and described in Letters Patent No. 212,420, grant ed to J. F. Applcby, February 18, 1879, (and since improved by various inventions) and is in the nature of an improvement on the mechanism for supporting the bindingcord .previous to forming the knot.

Hy invention consists in providing a novel device for operating a cord-supporting finger such as is described in my application for Let ters Patent tiled September 16, 1886, the serial number whereof is 213.682, the said cord-supporting finger being adapted to support the cord above and in advance of the bill-hook during the interval in which the usual knot-stripper and cord guide has moved out of its initial position when the binding-cord is severed after forming theprevious knot.

In the drawings, Figure 1 is a perspective view of the essential parts of a knotter,sl1OW- ing the cord-finger in the act of supporting the cord. Fig. 2 is a similar view showing the cordfinger thrown back out of the way and the cord in place guided by the usual cordguide and knotstripper. Fig. 3 is a face view of the cam for throwing the cordfinger back to the position shown in Fig. 2. Fig. at is an edge view of said cam, and Fig. 5 is an end elevation of the device for holding the cordfinger in place when not acted upon by the op erative parts.

Similar letters refer to like parts in the several views.

A is the knotter-frame, B is the breast-plate, G the tyer-whcel, D the bill-hook, E thetuckerfinger, F the cord-guide and knot-stripper, G

c is the tyer-wheel shaft, all constructed and arranged as usual.

Pivoted upon a stud, h, is the cord supporting finger H. Outside of the finger H. and upon the stud h is a spring, d, secured thereon by the washer i and pinj, the object of which is that the pressure of the spring d against the finger H may act as a check, preventing it from moving out of its place except when acted upon by the parts designed to operate it.

Upon the tyer-wheel shaft 0 is fixed the cam K, which acts upon the sliding rod L, one end of which slides through the perforated car a, formed on the knotter-fraine A, and the other end is bent to a right angle and is pivoted in the upper end of the cordfinger H abovcthe stud h, on which it is pivoted. The function of these operative parts is to throw back the cordfinger to the position shown in Fig. 2, the end of the rod L resting in the canrtrack k of the cam K when in the position shown in Fig. 1, and upon the plain surface of the cam when in the position shown in Fig. 2. Enlarged views of the cam K are shown in Figs. 3 and 4.

In the second or su ciplemental part-,f, of the stripper F is a pin, in, which projects through a slot formed in the cord-finger H at a point below the stud h, on which it is pivoted. The vibrating motion of the partf thus throws the cord-linger forward to the position shown in Fig. 1, the elongation of the slot allowing the cord-finger II to be held in place by the spring (1, although the pin m may have moved back.

The operation of my device is as follows, viz: The knotter being in the position shown in Fig. 1, and the needle-arm (not shown) retiring after a sheaf is bound, leaves the end of the cord in the cord-holder disk G and cord-holder shoe 1 (shown, principally, by dotted lines,) and lays the cord across the cordfinger H, as shown in Fig. 1. The tycr-whecl O and cam K now rotate in direction of the arrows, the incline a of the canrtrack 7; comes in contact with the end of the rod L, forcing it toward the tyer-wheel O, and throwing the lower end of the cordfinger back, as shown in Fig. 2, allowing the cord or to drop off the end of the cord-finger and into the usual cordnotch of the stripper F, as seen in Fig. 2, the stripper having been advanced for that purpose and a little in advance of the movement the cord-holderdisk, P is the cord-holdcrshoe, i of the cordfingcr by the usual cam-track, q,

in the tyer-wheel acting on the friction-roller p, pivoted on the extended end of the part f of the stripper F in the usual manner. The incline n of the earn-track 7c of the cam Khaving passed the end of the rod L, the rod remains stationary, as does the stripper F, until the tuckerfinger E, operated by the camtrack 1" of the tyer-wheel G, has acted on the cord and tucked it under the bill-hook D and the latter has rotated and tied the knot. cam-track q of the tyer-wheel now acts on the rollerp on the extended end of the partf of the stripper F, throwing it back to the position shown in Fig. 1 and stripping the knot from the bill-hook D, by which movement the pin m in the partf of the stripper F acts upon the cord-finger H, throwing it forward to the position shown in Fig. l in time to receive and support the cord 00 as the needle-arm (not shown) retires preparatory to the formation of another gavel.

Theforegoing operations are repeated at the binding of each sheaf.

Having now described my invention and stripper for th rowing said cord-finger forward into a position to receive the cord, a sliding rod pivoted to said cord-finger and adapted to be aeted on by a can]. to force it endwise and thus throw the cord-finger out of the way after having performed its function, and a suitable cam fixed to the tyer-whee1 shaft for operating said sliding rod, substantially as and for the purposes shown and described.

In testimonywhereofl have signed this specification, in the presence of two witnesses, this 18th day of April, A. D. 1887.
